Description

Cosmetic composition for removing fine dust or heavy metal}

The present invention relates to a cosmetic composition for removing fine dust or heavy metals, and more particularly, to a cosmetic composition capable of effectively removing fine dust or heavy metals adsorbed on the skin or preventing adsorption of fine dust or heavy metals to the skin.

The skin is the primary barrier of the human body and protects the internal organs from temperature and humidity changes, ultraviolet rays, pollutants, and other stimuli of the external environment, and plays an important role in maintaining biological homeostasis such as body temperature control.

External pollutants such as automobile emissions from urban areas and industrial parks, and yellow dust flying through the industrial zone in eastern China, including fine heavy metal powder, contaminate people's skin and may cause skin aging and skin troubles.

Heavy metal refers to all metals with a specific gravity of 4 or more, such as mercury, cadmium, lead, and copper. Generally, when absorbed into a living body, it is not easily discharged out of the body because it forms an organic complex that is not easily decomposed by combining with the substance in the body. It is a substance with strong properties that accumulate in organs and bones such as liver and kidneys. Long-term exposure to even a small amount of heavy metals can cause symptoms such as abnormal movement, ataxia, pigmentation and keratinization of the skin, atrophy of toenails and hair, impaired reproductive function, birth defects, decreased growth, and decreased immune function. Hazardous heavy metal fine dusts cause chemical reactions in the air to generate additional harmful substances such as nitrogen oxides (NO) and sulfur oxides (SO) to increase cytokines, causing inflammatory reactions on the skin, or skin problems such as atopy. Can cause. In addition, it is widely known that heavy metals destroy hyaluronic acid, which is closely related to the moisturizing of the skin.

Fine dust is a small air pollutant with a diameter of 10 μm or less floating in the atmosphere, and is much smaller than that of ordinary dust with an average particle diameter of 20 μm or more. Ultrafine dust has a diameter of 25㎛ or less, which is a quarter the size of fine dust. Ultrafine dust is 1/20~1/30 of the diameter of a hair, and its particles are very small, making it easy to penetrate into blood vessels, and circulate through the blood vessels throughout the body, causing an inflammatory reaction to increase oxidative stress on cells. According to the research results of the National Institute of Environmental Sciences, the major components of fine dust in the metropolitan area are sulfates, nitrates, and secondary products from China (data source: National Institute of Environmental Sciences in 2006). Fine dust penetrates deep into the human alveoli, accumulates in the bronchi and lungs, directly causes various respiratory diseases, reduces the body's immune function, causes asthma and breathing difficulties, and increases the concentration of heavy metals in rain or snow through long-distance travel. do. Because the size of fine dust in the skin is small, it can easily penetrate deep into the pores. If the infiltrated fine dust cannot be removed cleanly, it may cause inflammation and trouble in the skin.

The current method of removing heavy metals from the body is to inject complex compound-forming substances such as EDTA (ethylene diamine tetraacetate) and BAL (British Anti-Lewisite) to bind with the heavy metals accumulated in the body to discharge heavy metals out of the body, or vitamin B1. , Vitamin C and vitamin E are taken to prevent absorption of heavy metals in the body and facilitate their discharge. However, a method of effectively and easily removing heavy metals accumulated on the skin surface has not yet been proposed. As a technology for blocking fine dust in the related art, it is a technology that uses the repulsive force of the same charge and blocks fine dust, which is a negatively charged raw material in the formulation, or forms a network on the skin surface to prevent the penetration of fine dust into pores. It is disclosed. However, in reality, fine dust can have a positive charge as well as a negative charge, and the effect of blocking fine dust with the repulsive force of a specific charge is very insignificant, and the film-forming polymer cannot fundamentally prevent the adhesion of fine dust to the skin surface. There is this. In addition, fine dust can be removed to some extent by cleansing, but the finer the particle size of the fine dust, the more it is impossible to completely remove the fine dust that has penetrated deep into the pores. Therefore, it can be said that it is more important to prevent skin troubles by reducing the absorption and penetration of fine dust into the skin.

2. Measures the effect of removing fine dust or heavy metals from cleansing water or preventing skin penetration

Pig skin was used instead of human skin to measure the effect of removing fine dust or heavy metals or preventing skin penetration of the cleansing water (S1, S2, S3, S4). Meditinetics' MICROPIG® was used as the pig skin for experimentation, and Sigma Aldrich's Fine Dust (PM10-LIKE) was used as a sample of heavy metals and fine dust. First, cut the pig skin for experiment in units of 10 mm×10 mm, and put 30 ml of four types of cleansing water (S1, S2, S3, S4) and 1 mg of Fine Dust each prepared in 4 clean beakers, and then remove the pig skin. I put it in. Each of the four beakers prepared as described above is gently agitated for about 10 seconds with a vortex mixer, and then, with a scanning electron microscope (SEM), the pig skin coated with Fine Dust is in a diagonal direction, and three parts having the same unit area (unit area 1). , 2, 3) were counted. Table 2 below shows the number of particles detected in three areas having the same unit area when four types of cleansing water (S1, S2, S3, S4) were used. The unit areas 1, 2, and 3 all have a length of 2 mm×2 mm in the diagonal direction.

Classification of the measurement area Classification of cleansing water and number of particles (pcs) S1 S2 S3 S4 Unit area 1 8 43 49 38 Unit area 2 10 39 56 40 Unit area 3 11 42 51 43 Average 9.6 41.3 52.0 40.3

As shown in Table 2 above, when using cleansing water S1 containing all of illite powder, acrylic acid/acrylamidomethylpropanesulfonic acid copolymer, and xanthan gum as constituents, other cleansing waters S2, S3 and S4 are used. The number of particles decreased significantly compared to.
